Question about soundcore Liberty 4 NC

These headphones are suitable for moderate sports use. They are lightweight, comfortable for long training sessions, and have IPX4 certification to protect them from splashing water. Their Active Noise Reduction (ANC) feature allows you to isolate yourself from ambient noise in the gym or outdoors. However, their fit is not optimal for very intense activities such as CrossFit or HIIT, as they can move according to the shape of the ear. They are therefore suitable for moderate running or weight training, but not for very dynamic workouts.
